upgrading the stock ignition system on a bug

[advinnie]

Evening all I have a 2054cc motor powering my bug g at the moment and it really does shift but I'm still using the stock SVDA distributor for the timing no would I be better of upgrading the system to a crank triggered firing system like the one in the link below if so would I see better acceleration or just a smoother running engine?
The stock system is working just fine don't get me wrong but was wondering if I could get it working better.
here is the best nk to the kit I've seen. Any advice on this subject would be great cheers.

After much tuning(trail and error) or dyno time, you might eek out a few more HP. The smoother running may or may not happen, that might come if you are dealing with a weaker spark right now. The bigger question is, what fueling are you using? A single, a single dual throat or dual IDF/IDA's?

I have built, installed and tuned an MS system on my former Rabbit(Golf), initially it was maybe not as good as the CIS, then with time/tuning it became as good and then after more time/tuning and when my understanding came around about designing the spark table, it ran better than the CIS, it made more power, got better mpg's and I could reach into the car and turn the key and start it and walk away in sub-freezing temps in the morning.

Can I do that on my 2087 w/ dual IDF's w/ a GM HEI dist? No, only because it doesn't have chokes or the cold start ckt functional, but it sure runs smooth and it has no miss-fires that I can feel. It might not be as smooth as my MS'd motor was, but that motor wouldn't idle down to 400 rpm like this one will after I sync'd the carbs.

A hotter spark with an uprated coil might help you, depending upon what coil you have now. I did feel a noticeable difference when I changed coils on my Rabbit, and subsequent tuning on the fuel table showed it.

The biggest gain you get with a crank fired system is accuracy, there is no gear lash or slop to account for, so timing wander is eliminated.

Hi mate thanks for the reply. I'm running twin dual chock Dell 40's with the stock coil, plugs and distributor and on a cold start I have to use the throttle cause there's no chocks but only for 30 seconds or so then she is as steady as a rock no miss firing at all plus if I what I can lower the idle down to 500 rpm but I keep her at 850 rpm. She goes just fine was just wondering because I've modified every part of the engine now except the ignition if I should do that as well but I think I will just leave her alone you know the saying " if it ant broke don't fix it "
A friend of mine has just send me a link witch is below with a CDI system but I'm not to sure if it's worth fitting one or not what's your thoughts?

The biggest thing you'd get from something like that, is the points would last longer. Before I made the move to MS, I had an MSD box connected between the points dist and the coil, there was a better idle with the MSD and the points would last until the pivot or rub block would just plain wear out. You could get some extra out of one of those, but you are still totally dependent upon the timing/trigger input of the dist.

If it were me, and the dist was in good condit-ion, no shaft play, good smooth working advance/retard, I'd get a pertronix module to eliminate the pointsand then get a higher voltage coil and some nice 8-10mm plug wires and be done with it. Then you don't have to worry about points wearing. But, carry a kit to go back to them if the pertronix kit fails.

What I like about my HEI dist is I can walk into any auto parts store here in the USA and buy a cap, rotor and/or module if something ever fails.

And a lot of what you may or may not need will depend upon how you drive/use this car. My car was built as it is now some 20+yrs ago by my father as a driving car. Then it sat for almost 20yrs till now and I drive it around town, in the mountains and auto-x it, this last year was it's first year on the road and it never failed to perform for me.

I think I will stick with want I've got she has never let me down yet. I use the bug all the time for town driving when the weather is good and every now and then when the roads are clear I do love to put my foot down
Once again cheers for your help mate.
